看了user guide,找到如下的话,研究一下:
Ad Hoc Requirements
You can issue and return components that do not appear as job or schedule material
requirements using the ’Specific Component’ option. When you issue or return
components using this option, the system determines if the item is a material
requirement for the job or schedule. If the item is not a material requirement, is a
backflush component, or is not required at the operation sequence a warning message is
displayed, but you can continue with the transaction. Components added in this manner
are commonly referred to as ’ad hoc’ components.
Bulk, Supplier, and Phantom Components
You can issue Bulk, Supplier, and Phantom supply type items, which do not normally
appear as requirements in the WIP Material Transactions window, using the ’Specific
Component’ option. |
